Post with HTTPS

Hello, I have some time thinking and the Codex did not solve much. I managed to make the administration panel login and be done with https, but I need that when a user enters http://www.miweb.com/formulario, connect via https, ie https://www .miweb.com / form. The rest of the pages, and everything else (except the access panel) with https would be normal. Looking at the Codex says that I put the following in the file wp-config.php: define (‘FORCE_SSL_LOGIN’, true) define (‘FORCE_SSL_ADMIN’, true), but this is for everything related to the administration panel / login . Does anyone could help me?
